you could give a unit another unit-form with an ethereal armor type then change its form depending on what it should be doing, just spitballing
Edit: sorry i read your previous post about the units still being attackable, you could make all of your units ground units except those that have the ethereal form and make it air
Perhaps anyone got a clue how to apply a banish effect to a unit? Not just a vortex coloring and banish special effect, but also the way the target shines when it's banished. There must be an effect for this somewhere.
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
